STAND-LAMP CONSTRUCTION.

Application filed June 5,

My invention relates to stand lamp construction and more specifically to a stand lamp cluster provided with switches.

One of the objects of my invention is to provide a stand lamp construction which will be simple, durable and eflicient.

A further object of my invention is to provide improved supporting means for the lamp contacts, switches and housing Further objects will appear from the description and claims.

In the drawings, in which an embodiment of my invention is shown I Figure 1 is an axial section of the stand lamp;

Fig. 2 is a plan view of the lamp with the upper part of the housing removed;

Fig. 3' is a section on the line 3-3 of Fig. 2; and

Fig.- 2.

Referring now to the drawings in detail, the construction shown comprises a "tubular pedestal '10, which may be of metal tubing,

45 is a section 0111311811116 4+4 of affording a passage for the feed wires 'to the lamp, an insulating base 11 which may be a heavy fiber disk, shell and center receptacle contacts 12 and 13 mounted on the insulating base, a pair of switch mechanisms 1 1 for controlling the two lamps, also mounted on the insulating base, a sheetmetal housing 15 for enclosing the base, contacts, switch mechanisms, etc, mounted thereon and a shad-e-supporting frame 16- suprported above the housing 15.,

For mounting the insulating base' 11 on thetubular pedestal 10, a metal bracket 17 I is provided having a flange portion 18 clamped against the lower face of the insulating disk 11 and having a tubular por tion 19 into' which the upper end of the tubular pedestal is screwed. For supporting the upper part of the housing- 15' and the shade-supporting frame 16', a bracketa20 isprovided having foot or flange portions 21 clamped against the upper face of the insulating disk 11, and having a U-shaped standard portion 22 to which a screw 23 is riveted, the upper part Of the casing 15 and the shade-supporting frame being clamped on this standard by means of the nut 24 threaded Onto the screw 23.

The brackets 17 and 20 are clamped on the insulating disk 11 by meansof screws 24? and nuts 2t".

1924. Serial No. 718,039.

The two shell receptacle contacts 12 are mounted on a V-shaped stamping 25 which, in turn, is mounted on the insulating disk 11. A binding screw 26 is provided, electrical'ly connected with one end of this V- shapcd stamping, to which binding screW one of the feed wires is secured. The lower bowl-shaped portion, 27 of the casing 15 is held in place by means of a pair of insulating bushings 28 having flanges 29 for engaging the casing member 27 and having sleeve portions 30 threaded onto the shell contacts 12. Each receptacle center contact member 13 is formed as a part of an integral metal stamping 31 secured to the insulating disk 11 by means of screws 32 and nuts 33. Each of these stampings is provided with a switch frame member 351 in which one end of the switch shaft 35 is mounted. The other end of the switch shaft is mounted in a switch frame member 36 and secured to the insulating disk 11 by means of screws 37. A commutator 38 is rotatably mounted on the switch shaft for electrically connecting and disconnecting the spring contact 39 with respect to the switch frame member 31. Current is supplied to both of the spring contact members 39 by means of a conductor strap 10' held in place on the insulating disk 11 by means of the screws 41 and nuts 42 which also hold the spring contacts 39 in place and electrically connect the conductor strap with the spring contacts 39. A binding screw 13 is threaded onto this metal conductor 10 to which binding screw the other feed wire is secured.

' The circuit is from the binding screw 43 through the conductor strap 40,,screwf1l, spring contact 39, commutator 38, switch framemember 31, center contact 13, lamp,

shell contact 12 and stamping 25 to thewiri'ng' terminal 26.

While I have shown'but one. form of my invention, it is obvious that it may be embodied in other forms covered and defined by the claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is 1. A stand lamp comprising a tubular pedestal affording a passage for the feed wires, a metal bracket secured to the upper end of said pedestal, an insulating base mounted on and above said bracket and lying in a general horizontal plane, a second bracket mounted on and above said insulating base, lamp receptacle contacts mounted on said insulating base and positioned to hold the lamps so that they extend downwardly and outwardly with respect to the axis of the pedestal, a shade support mounted on and above said second bracket, and a metal housing for said brackets, insulating base and receptacle contacts having openings for the insertion of the lamps.

2. A stand lamp comprising a tubular pedestal affording a passage for the feed wires, a metal bracket secured to the upper end of said pedestal, an insulating base mounted on and above said bracket and lying in a general horizontal plane, a second bracket mounted on and above said insulating base, lamp receptacle contacts mounted on said insulating base and positioned to hold the lamps so that they extend clownwardly and outwardly with respect to the axis of the pedestal, a shade support mount ed on and above said second bracket, and a metal housing for said brackets, insulating base and receptacle contacts, comprising a hood mounted on and above said second bracket and extending down to substantially the plane of the insulating base, said housing having openings for the insertion of the lamps.

3. A stand lamp comprising a tubular pedestal affording a passage for the feed wires, a metal bracket secured to the upper end of said pedestal, an insulating base mounted on and above said bracket and lying in a general horizontal plane, a second bracketmounted on and above said insulating base, lamp receptacle contacts mounted on said insulating base and positioned to hold the lamps so that they extend clownwardly and outwardly with respect to the axis of the pedestal, a shade support mounted on and above said second bracket, and a metal housing for said brackets, insulating base and receptacle contacts, comprising a hood mounted on and above said second bracket and extending down to substantially the plane of the insulating base, and a cup meeting said hood and housing said receptacle contacts said cap having openings for the insertion of the lamps.

4. A stand lamp comprising a tubular pedestal affording a passage for the feed wires, a metal bracket secured to the upper end of said pedestal, an insulating base mounted on and above said bracket and lying in a general horizontal plane, a second bracket mounted on and above said insulating base, lamp receptacle contacts mounted on said insulating base and positioned to hold the lamps so that they extend downwardly and outwardly with respect to the axis of the pedestal, a shade support mounted on and above said second bracket, and a metalhousing for said brackets, insulating base and receptacle contacts, said insulating base being clamped between said brackets said housing having openings for the insertion of the lamps.

5. A stand lamp comprising a tubular pedestal affording a passage for the feed wires, a metal bracket secured to the upper end of said pedestal, an insulating base mounted on and bove said bracket and lying in a general horizontal plane, a second bracket mounted on and above said insulating base, lamp receptacle contacts mounted on said insulating base and positioned to hold the lamps so that they extend downwardly and out-wardly with respect to the axis of the pedestal, a shade support mounted on and above said second bracket, and a metal housing for said brackets, insulating base and receptacle contacts, and screws extending through both of said brackets and said base for clamping the base between the brackets said housing having openings for the insertion of the lamps.

6. A stand lamp comprising a tubular pedestal affording a passage for the feed wires, a metal bracket secured to the upper end of said pedestal, an insulating base mounted on and above said bracket and lying in a general horizontal plane, a second bracket mounted on and above said insulating base, lamp receptacle contacts mounted on said insulating base and positioned to hold the lamps so that they extend downwardly and outwardly with respect to the axis of the pedestal, a shade support mounted on and above said second bracket, and a metal housing for said brackets, insulating base and receptacle contacts, said second bracket comprising an intermediate portion to which said shade support is secured and two arms extending downwardly and outwardly from said intermediate portion and secured to said base said housing having openings for the insertion of the lamps.

In witness whereof, I have hereunto subscribed my name.
